Introduction

# Welcome to the 'steroid data analysis' webpage! 

# The procedures and explanations to make all the analysis and plots are in their individual chapters below. 
# These methods could be also easily applied to other types of data sets and metabolites than 'steroids' and their respective metadata per se. 
# In addition, there is a small 'disclaimer' also at the end of this webpage to emphasize that this site is mainly for educational purposes.
# Please let me know if you have any questions. For that, use the 'following' email: patati at the university of Turku

Importing Data and Metadata

# First set your data folder:
# setwd("C:/Users/patati/Documents/GitHub/Steroid_Data_Analysis")
# or:"C:/Users/patati/Desktop/Turku/R" #check the wd with: here::here() #or getwd()
# load("thereal.RData") #This is so to say real data, and it is not available here (at the site).

# It is easier to load the ready stiched data in one go with .RData file than one by one as below, but
# for educational purposes I put some examples what may need to be done to get your data in ok form 
# for later purposes
